The potential for renewable energy is pretty incredible. Our planet can churn out a lot of juice without burning a single lump of goal or a single drop of oil. One of the greatest renewable resources is the sea, which is why, as Reconstruct reports, the Swansea Bay Tidal Lagoon will use the natural rise and fall of the ocean tides to generate power.
It’s not yet complete, but when it is, it will power 155,000 homes and won’t likely need to be replaced for a whopping 120 years. It will replace about a quarter million barrels of oil each year and have almost no carbon footprint.
Tidal power has been around since the 60’s, so it’s not exactly a new concept. What is new is how Swansea Lagoon plans to do it.
Swansea will create a six-mile-long barrier wall that will enclose a rather large amount of water in an artificial tidal lagoon.
